3 Claims.

This invention relates to new and useful improvements in razors and moreparticularly it pertains to razors of the power driven type.

One of the objects of the present invention resides in a new andimproved type of power razor having the cutting head offset with respectto the main body portion whereby more effective operation with lesseffort on the part of the operator is obtained.

All suchrazors with which I am familiar require an awkward position ofthe arm of the operator, and it is a further object of the invention soto construct a razor of this type that, during use, the arm may be heldclosely pressed against the body, the most comfortable and practicalposition during the shaving operation.

A further object'of the invention resides in a new and improvedconstruction whereby the cutting edge of. the razor may be adjusted withrelation to the surface over which it is moved in order that a moreeffective and complete shaving operation may be accomplished by theinstrument.

Still a further object of the invention resides in theprovision. ofmeans whereby the surface being operatedupon may be illuminated whilethe device is in use.

Still a further object of the invention resides in a new and novelconstruction and arrangement of parts whereby the short lengths of hairclip ped or cut by the instrument will be collected and will not beshowered or allowed to fall upon the person of the operator.

Still a further object of the invention resides in a novel constructionof removable cutting element which is of such construction as to renderthe; cutting element readily replaceable at any desired time,

Still a. further object of the invention resides in the provisionofmeans for rolling o-r distorting the surface over which the razor isoperating in order to more effectively perform a shaving operation.

Still a further object of the invention resides in the provision of anovel construction whereby implements other than cutting implements maybe supported by the device and removably connected therewith at will.

In my instrument, the main body portion or housing constitutes the gripor means by which the instrument is manipulated, and a further ob jectof the invention resides in a new and improved form of grip whereby moreeffective manipulation of the instrument is had.

Other objects of the invention will appear as the nature thereof isbetter understood, for which purpose ref erencewill be had to thefollowing specification and claims and the accompanying drawing,wherein:

Figure, 12 is a perspective view illustrating another modified form ofsaid invention.

Referring to the drawing by reference character, the device comprises amain body portion I5.. This main body portion is in the form of ahousing having a removable cover plate 16 by which access may beobtained to the interior of said housing. Mounted within the main bodyportion and herein conventionally shown, there is an electric motor ll,the power for which is supplied by means of a suitable conductor IS. Thearmature of the motor is designated I9 and includes a projecting powerarm 20 which, in Figure 1, moves right and left about a pivotalpoint-22.

By reference to Figures 2 and i, it will be noted that the body portionhas two arms 25 and 26 projecting therefrom and these arms extend at anangle to the longitudinal axis of the body portion 55. The arms 25 and26, by reason of their position with respect to the main body portion,constitute an angularly disposed implement supporting means. The arm 26,see Figure 5, is provided with a curved groove or channel 21, while thearm 25 is provided with a bearing opening 23. The reference numeral 29designates a shell which is a little more than semi-circular in crosssectional form and, as best illustrated in Figure 6, this shell 29 has alongitudinally extending slot 39 extending from its free end inwardly ofthe body portion of the shell. One end of the shell is closed as at 3!and projecting from the closed end 3i there is a stub shaft or pintle 32for reception in the bearing portion 28 of the arm 25, it beingunderstood that the arm may be slotted as at 33 to permit of insertionof this stub shaft or pintle 32. A spring or similar resilient member 33 is carried by the main body portion and has an opening for thereception of the stub shaft or pintle 32 to retain it in position in theslot 33. The opposite end of the shell 29 is received in the curvedgroove 27, as best illustrated at 35 in Figure 5. This constructionprovides means for mounting the shell 29 in such a manner that it may beoscillated within the implement supporting means and, as a means foroscillating this sleeve as above described, a lever 36 may be rigidlysecured to the shell and extend rearwardly thereof, as best illustratedin Figure 2. This lever is preferably curved or angularly formed so thatwhen in its normal position it will be parallel with the face 38 of themain body portion and in such position that when the implement isgripped by the operator the free end of the lever 36 will be in aconvenient position to permit of adjustment of the shell 29 during ashaving operation.

Mounted within the shell 29 is the cutting element of the razor. Thiscutting element comprises a tubular member 40 having an inwardlydisposed portion 4| and a longitudinally extending slot 42. That area ofthe tubular member ll! which lies closely adjacent the depressed portion4| on opposite sides thereof, together with the depressed portion 4!, isprovided with a plurality of fine slits 42. The depressed portion ilprovides two shoulder-like portions 53 on opposite sides of thedepressed portion, the purpose of which will be hereinafter described.

The other element of the cutting means comprises a solid cylindricalmember :5 which is provided with a longitudinally extending groove at.The portions on opposite sides of the longitudinally extending groove 46 are formed with a plurality of fine slits 41. The member is adapted tobe received within the tubular member 40 with the depressed portion 4!of the tubular member 40 occupying a position in the longitudinal groove$5 of the member d5.

This construction provides a cutting element which operates in thefollowing manner. As the device is moved over the face or surfaceoperated upon, the hair projects through the slits 42 of the tubularmember 4& and is sheared off by the elements formed by the rooves d1 ofthe member 45. as the member 45 is reciprocated within the tubularmember All. It is to be understood that the member 45 is positionedWithin the tubular member 4!) and that both members, when so assembled,are positioned within the shell member 29 to form the cutting elementwhich is positioned in the angularly disposed implement su portingportion of the tool.

Means is provided to connect the member 55 with the power arm 2!] of themotor, and this means comprises a pair of pins 55 which are carried bythe member 45 and extend therefrom. In the assembled position of thecutter, the pins occupy a position in the slot 32 of the tubular memberand the slot 30 of the shell 29, and the parts are so proportioned thatin this position the free end of the power arm 21] will lie between thepins 58, as best illustrated in Figures 1 and 4, in such a manner thatas the power arm 20 is moved in a right and left direction, asheretofore described, the member i5 will be reciprocated to effect ashearing operation, as above described.

In moving of the implement over the face, the shoulders 55, heretoforementioned, tend to distort the skin causing it to roll upwardly into thedepressed portion l of the tubular member 40, thus providing for acloser clipping of the hair than is obtainable with such devices asordinarily constructed.

During the shaving operation, the cutting element may be adjusted to aproper cutting rela tion with the surface operated upon merely byoperation of the lever 36. As heretofore stated, the lever 35 is curvedand is of such shape that if maintained in a position in which it issubstantially parallel with the surface being operated upon, the propercutting angle will be had. Thus, it will be apparent that by thisconstruction, if it appears at any time during the operation that thecutting element is not properly adjusted with respect to the surfaceoperated upon, the proper adjustment may be made merely by rocking thelever to the proper position.

The reference numeral 50 designates a housing carried preferably by thetop wall of the main body portion and this housing forms means forsupporting one or more illuminating lamps 6|, which are so positioned inthe housing as to throw their beams directly upon the surface operatedupon at the point where the operation is taking place. Current may besupplied to this illuminating means by a suitable conductor 62.

It will be noted by examination of Figures 3 and 4 that the outersurface 64 of the main body portion is convex while the inner surfacedesignated 65 is concaved, which construction provides a free, easy andcomfortable grip of the instrument by the operator.

As illustrated in Figure 7, the member 45 of the cutting element isprovided with a passage 65 extending therethrough, and this passageprovides a compartment into which the clipped ends of hair are receivedto prevent showering thereof over the person of the operator. As theclipped ends accumulate they may be removed merely by disassembling thecutting element and cleaning thereof.

In Figures 8 and 9 I have illustrated a slightly modified form of razor.In this form of the invention the shell 29 constitutes a holder and therazor is carried by a rigid arm 66 projecting from a member 61 which iscircular in cross section and which is adapted to be received within theshell member 29, as illustrated in Figure 8. A pin 68 receivable in theslot 39 of the shell member 29 prevents rocking movement of the memher6? within the shell and forms the operative connection between the shell29 and the member 5'1, whereby the member 61 may be rocked by the lever36. In this form of the invention the razor comprises a reciprocatingblade '16 from the rear edge of which project two pins Tl which embracethe power lever 752 of the motor, which in this instance may be slightlylonger than in the heretofore described form of the invention. The blade79 is reciprocated in the housing 14, which comprises a rear wall 15, abottom wall 76 and a removable top Wall l7. Interposed between the blade70 and the bottom Wall 18 there is a bushing plate to provide for morefree and easy reciprocation of the blade 19. The entire device may beheld in assembled relation by means of a bolt 19 having a wing nut 8|]thereon which passes through the member 11, the bottom wall It of thehousing and the blade 19. The member "i1 preferably consists of a verythin plate of highly tempered resilient metal and by adjustment of thewing nut 8|] the tension which this member exerts upon the razor blade10 may be adjusted. The member 11 is also formed with guard teeth 8|while the blade 19 is formed with cutting teeth 82 which cooperate withthe guard teeth 8| when the blade is reciprocated to effect a shearingoperation. The member 'Il may have that face which contacts the razorblade plated and the adjacent contacting face of the razor blade maylikewise be plated.

In Figure 10 I have illustrated a device for clipping hair ininaccessible locations, of which the nostrils of the nose are one verygood example. In this device a solid member 90 is provided which isadapted to be received within the shell 29. A yoke 9| is rigidly carriedby the solid member 99, and projecting therefrom there is an element 92having guard teeth 93. The element 92 is relatively narrow and thenumber of guard teeth projecting from the end thereof is reduced to aminimum. The member 92 is rigidly carried by the yoke 9| and pivotallymounted as at 94 in the yoke there is a cutting element 95 the forwardend of which is provided with cutting teeth 96 which cooperate with theguard teeth 93 of the member 92 to effect a shearing operation when themember 95 is rocked about its pivotal point 94. Means is provided torock the member 95 about its pivotal point 94, and this means includes aright angular extension 91 which is notched as at 98 to receive thepower arm 12 of the motor.

In Figures 11 and 12 the device is of substantially the sameconstruction as that illustrated in Figure 10. Instead, however, of theimplement in Figure 11 being a cutting implement, the arm 95 may beprovided on its outer end with an abrading element I90 which ispreferably in the form of a nail file and a bufflng element IOI, whilein Figure 12, the arm 95 may be provided with a brush I95 upon its outerend which may be in the form of a tooth brush or a brush of any otherdescription.

From the foregoing it will be apparent that the present inventionprovides a new and novel instrument in which the several objects abovementioned are accomplished.

It is to be understood that this invention is not to be limited to thespecific constructions herein shown but that it may be practiced inother forms without departing from the scope of the appended claims.
